Seek

Seek behaviour causes flock members to attempt to steer towards a specified target. It is the most basic of all steering behaviours and it simply requires a target position to be provided to the system.

Seek behaviour will cause a boid to move towards the target as fast as the system will allow it to. However, if the target is static boids can often end up overshooting the target location and need to reverse back in the opposite direction and approach again. This results in a flip-flop type of movement which is not necessarily very realistic.

To counter the flip-flop movement, another technique called Arrival can be used.
